Jiddu Krishnamurti said this quote
“ Patriotism, whether it is of the Western kind, or of the Eastern kind, is the same, a poison in human beings that is really distorting thought. So patriotism is a disease, and when you begin to realize, become aware that it is a disease, then you will see how your mind is reacting to that disease. When, in time of war, the whole world talks of patriotism, you will know the falseness of it, and therefore you will act as a true human being ”
